Where can I find a 3D Elevation Program (3DEP) DEM status map and get information on recent updates?
Status maps showing 3DEP product availability and recent updates can be found on the 3DEP Product Availability web page.
Areas containing recent updates are refreshed on a monthly basis. Spatial metadata shapefiles showing the updated areas for each product are also available for download from the 3DEP Product Metadata web page.
Product updates can be acquired through The National Map Download Client or through a bulk data request (see here for information on bulk data delivery).

Coastal National Elevation Database
The Coastal National Elevation Database (CoNED) Applications Project develops enhanced topographic (land elevation) and bathymetric (water depth) datasets that serve as valuable resources for coastal hazards research (Danielson and others, 2016; Thatcher and others, 2016). These datasets are used widely for mapping inundation zones from riverine...

3D Elevation Program—Virtual USA in 3D
The U.S. Geological Survey (USGS) 3D Elevation Program (3DEP) uses a laser system called ‘lidar’ (light detection and ranging) to create a virtual reality map of the Nation that is very accurate. 3D maps have many uses with new uses being discovered all the time.

Cartographers in the Field
This Depression-era oil painting was created by USGS field man Hal Shelton in 1940. The painting depicts mapping techniques used in the early days of cartography, including an alidade and stadia rod for determining distances and elevations and a plane-table for sketching contour lines. A USGS benchmark is visible near the top. The straight white lines represent survey
